I am trying to use estimateRigidTransform but I am getting error error C2039: 'estimateRigidTransform' : is not a member of 'cv' I have included include <opencv2 core="" core.hpp=""> include <opencv2 imgproc="" imgproc.hpp=""> include <opencv2 highgui="" highgui.hpp=""> include <opencv2 features2d="" features2d.hpp=""> include <opencv2 nonfree="" features2d.hpp=""> include <opencv2 calib3d="" calib3d.hpp=""> include <opencv2 ts="" ts.hpp="">
what I am missing so that estimateRigidTransform can not be recognized
